Why did George IV demolish Carlton House? It seems to have been very, very grand.
-Duke of NJ
Perhaps too expensive to maintain? It was replaced by 2 houses eventually. Here's a photo from wikipedia (also some of the info on the house):

"Holland began working first on the State Apartments along the garden front, the principal reception rooms of the house. Construction commenced in 1784; when these rooms were visited in September 1785 by the usually critical Horace Walpole, he was impressed, writing that when completed, Carlton House would be "the most perfect in Europe".
"There is an August simplicity that astonished me. You cannot call it magnificent; it is the taste and propriety that strike. Every ornament is at a proper distance, and not one too large, but all delicate and new, with more freedom and variety than Greek ornaments; and, though probably borrowed from the Hotel de Condé and other new Palaces, not one that is not rather classic than French.
By the end of 1785, however, construction at Carlton House came to a halt because of the Prince of Wales' mounting debts: his unpaid bills following his marriage to Mrs Fitzherbert amounted to £250,000. Parliament appointed a commission to investigate the huge cost overruns at Carlton House, and to draw up estimates on how much would be needed to complete the project. In May, 1787, the Prince of Wales contritely approached his father, King George III, and persuaded him to provide the money to finish the house. When work resumed in the summer of 1787, with a budget of £60,000 to finish the house, it was with the assistance of many of the leading furniture makers and craftsmen of France. (The onset of the French Revolution soon ended all French royal and aristocratic commissions.) These French workers who contributed to this second phase at Carlton House were under the design supervision of the Parisian marchand-mercier Dominique Daguerre, who was the interior decorator for Marie Antoinette; and who was the agent through whom furniture by Adam Weisweiler was imported for the house.
When completed, Carlton House was approximately 202' long, and 130' deep. Visitors entered the house through a hexastyle portico of Corinthian columns that led to a foyer that was flanked on either side by anterooms. Carlton House was unusual in that the visitor entered the house on the main floor. (Most London mansions and palaces of the time followed the Palladian architectual concept of a low ground floor (or rustic) with the principal floor above.) From the foyer, the visitor entered the two story top lit entrance hall that was decorated with Ionic columns of yellow marble scagliola. Beyond the hall was an octagonal room that was also top lit. The octagonal room was flanked on the right by the grand staircase and flanked on the left by a courtyard, while straight ahead was the main anteroom. Once in the anteroom, the visitor either turned left into the private apartments of the Prince of Wales, or turned right into the formal reception rooms: Throne Room, Drawing room, Music Room, Dining Room.

Many of the finest paintings now in the royal collection were collected by George IV for Carlton House. When Prince of Wales, George IV patronized contemporary artists such as Reynolds, Gainsborough, and Stubbs. With the Third Marquess of Hertford and Sir Charles Long acting as his art advisors, George IV also bought Old Master paintings by Rembrandt, Rubens, Van Dyck, Cuyp and Jan Steen. An 1816 inventory of Carlton House showed 136 pictures in the State Rooms, a further 67 in the Prince of Wales' private suite, and another 250 in other parts of the house."
